The only thing that I can think of between the HD65 and the LCD is resolution and/or the refresh rate. Other than that I would say this is a head-scratcher.
Projector is Optoma HD65. I'm running windows 7. It did for a while but now my computer does not detect my HMDI projector. The projector will work connected to a DVD player with the same HDMI cable and my LCD TV works fine connected to the computer as a 2nd display. Again, with the same HDMI cable. Hence, the physical connection (HDMI port/HDMI cable) is not source of the problem. I've updated my video drivers and gone into my display settings and tried to "force detect" the projector to no avail. The computer simply will not detect the projector as a second display device. I'm totally baffled. Any advice will be greatly appreciated!
